MVHR installation in Bath
Whole-home heat recovery ventilation, designed room by room and airflow-tested at handover. Covering Bath and BA1, BA2 and BA15.
- From £4,625 inc VAT per home
- Free survey
We survey Bath homes for MVHR before quoting, because the duct routes decide the price more than the unit does.
Whether the property is in the middle of Bath or one of the villages around it, the process is the same: a look at the building, a written price, then fitting and testing on the agreed day.

How we approach MVHR in Bath
MVHR works best in a home that is reasonably airtight: a new build, a deep retrofit with insulation and new windows, or a renovation where ceilings are coming down anyway. In a draughty older house it still ventilates well, but less of the heat-recovery benefit is felt because warm air escapes through gaps instead of the unit.
Radial semi-rigid ducting
One small duct per valve from a manifold. Quieter and easier to balance than branched rigid duct in most homes.
Summer bypass and boost controls
Bypass lets cooler night air in without heat recovery; humidity or switch boost for showers and cooking.

Questions from Bath
Do you cover Bath and nearby?
Yes. We cover Bath and nearby places including Keynsham, Neston, Trowbridge and Midsomer Norton. Send your postcode and we will confirm.
Can MVHR cool the house in summer?
MVHR is not air conditioning, but a summer bypass lets cooler night air in without warming it, which helps take the edge off hot rooms. For real cooling you would need a separate system.
How much does MVHR cost to install?
A typical retrofit costs £6,450 to £9,450 including VAT for a three-bedroom house, and £4,950 to £7,950 when it goes in during a new build or full renovation. Flats start lower and large detached homes cost more because of the duct runs. We give a fixed price after the survey.
What is the price of MVHR in Bath?
